5.28 Simple harmonic motion. For Problems 5.26 through 5.31 A follower rises 4 in in 180° of cam rotation and then returns during the next 180° of cam rotation. The cam rotates at 60 rev/min. For the given follower motions, determine: (a) mathe- matical expressions for the displacement, velocity, acceleration, and jerk of the follower; (b) the magnitudes and locations of maximum velocity and maximum acceleration of the fol- lower; (c) the follower displacement, velocity, acceleration, and jerk when the cam angle is 120°; and (d) the follower displacement, velocity, acceleration, and jerk when the follower displacement is 3 in during the rise segment of the motion.
